Local control allows charging based on preset mains and photovoltaic charging voltages. Battery discharge is protected by backfeed protection, disconnecting the load when the battery charge falls below 10%. Automatic control allows for remote configuration parameter updates and allows for remote selection of photovoltaic or mains charging. This system also features a wind turbine backup UPS function, providing a reserved interface when the miniature circuit breaker F6 output is disconnected, allowing for uninterrupted DC 24V operation of the wind turbine's main control system.
